中固化学® 369 is a highly efficient UV curing agent which is used to initiate the photopolymerisation of chemically prepolymers – e.g. acrylates – in combination with mono- or 多官能单体s.
中固化学® 369 is especially suitable for pigmented UV curable systems, photoresists and printing plates.
中固化学® 369
Chemial Name: 2-Benzyl-2-(dimethylamino)-4-morpholinobutyrophenone
Synonym: IRGACURE 369;Genocure BDMM;Photoinitiator 369;Chivacure 169;Speedcure BDMB;TK 11-319;Omnirad 369;IHT-PI 910; BDMM Photoinitiator
CAS No: 119313-12-1
Molecular Formula: C23H30N2O2
Molecular Structure:
中固化学®369 is an efficient UV curing agent for initiating UV polymerization of unsaturated prepolymerized systems. After the photoinitiator is irradiated by ultraviolet light, it absorbs the energy of the light and splits into two active free radicals, which triggers the chain polymerization of the photosensitive resin and the active diluent, which is characterized by fast speed, environmental protection and energy saving.

中固化学 369 can be used alone or in combination with suitable coinitiators, such as 中固化学 184 and 中固化学 BDK, for UV curable inks and varnishes for applications on paper, metal and plastic 原料组分s. Its high absorptivity makes it especially suitable for UV curable inks,graphic arts (e.g. offset and screen inks, printing plates, etc.) and in the electronics industry (e.g. photoresists, solder masks, etc.).
